I have been trying to change my SSL certificate for my website xecutiv.net from Flexible to Full (Strict) for some time now.
But I do not succeed.
I have started many attempts and unfortunately I have always failed.
I got my certificate of origin at Cloudflare and uploaded it to my server.
I connected the Key and PEM file to the default-ssl.conf file and I can’t get any further since then.
You always get the error 521 when you visit my website and I have no idea why.
Can someone please give me an answer to this I need it urgently!
I have now dealt with it and managed to get the server to listen on port 443. But now there is a new error. Instead of error 521 I now get 525. Some handshake did not work. Do I just have to wait or is this a serious error?
Waiting won’t help. It has an invalid certificate. If it’s the Cloudflare Origin certificate for that domain, it should work with Full (Strict). It will probably work with Full (not strict), but you may have to re-try generating an Origin Certificate for that domain reinstalling it. Then re-start the web server to load the new certificate.
